A $$200/1$$ current transformer $$(CT)$$ is wound with $$200$$ turns on the secondary on a toroidal core. When it carries a current of $$160$$ $$A$$ on the primary, the ratio and p...

The core flux in the $$CT$$ of above problem under the given operating condition is

Instrument transformers are known to introduce magnitude and phase errors in measurements. These are primarily due to
